Benchmarks

Gambas is an interpreted language, with no "just-in-time" or other compilation to native code at all up to the 3.2 version.

Here is some little benchmarks mostly stolen on the Internet used for comparing Gambas and Gambas JIT-compiled with interpreted Python and Perl.

The tests were done on my own computer, by running them with the time system utility. The execution time is the sum of the user time and the system time.

Note there is a little time used for compiling the source files in all languages.

Almost all benchmarks are stupid, and absolute results may vary between two successive runs.

Benchmark source code

To get the source code of the benchmarks, browse the benchmark directory in the Gambas source code.

Run the benchmark on your own system

There is a script named benchmark.gbs in the benchmark directory. Just open a terminal, change to that directory, and run it.

You will get the result as HTML data. If you want to share it, don't forget to specify which distribution you run and your CPU model.

For example, on my own system (with 8 cores, hence the repeated lines):
